I have a problem, where, when trying to readjust the screen, the text that is inside a TextFlow , goes out of the screen, and is not set down.

public SwingFXPanel(ServicosJson json) {
    this.json = json;
    this.cliente = cliente;        
    this.msgs = new ArrayList<>();               
    this.chatBox = new VBox();                            
    this.scroll = new ScrollPane();                
    this.lista = new ArrayList<>();
    this.scroll.setAccessibleRole(javafx.scene.AccessibleRole.PARENT);
    this.scroll.setHbarPolicy(javafx.scene.control.ScrollPane.ScrollBarPolicy.NEVER);
    this.scroll.setLayoutX(0);
    this.scroll.setLayoutY(0);
    this.scroll.setPrefHeight(735);
    this.scroll.setPrefWidth(519);        
    this.scroll.setVvalue(1.0);        
    this.scroll.setFitToHeight(true);
    this.scroll.setFitToWidth(true);         
    this.scene = new Scene(this.scroll);
    this.scene.getStylesheets().add(getClass().getResource("/br/com/teste/commerce/chat/css/style.css").toString());    
    this.chatBox.heightProperty().addListener(observable -> scroll.setVvalue(1D));
    thread = new Thread(new Runnable() {
        @Override
        public void run() {
            //
        }            
    });        
}

public void addMessage(String mensagem, String origem, boolean mostrandoAtalhos) {
        mensagem = mensagem.replace("u000A", "\n");
        Text text=new Text(mensagem);
        text.setFill(Color.BLACK);        
        text.getStyleClass().add("message");
        TextFlow tempFlow=new TextFlow();                     

        if(origem.equals("0")){            
            Text txtName=new Text();
            txtName.getStyleClass().add("txtName");
            tempFlow.getChildren().add(txtName);
        }
        if (mostrandoAtalhos) {
            text.setWrappingWidth(20);
            tempFlow.setMaxWidth(300);        
        } else {
            text.setWrappingWidth(80);
            tempFlow.setMaxWidth(650);        
        }
        tempFlow.getChildren().add(text);                
        TextFlow flow=new TextFlow(tempFlow);
        HBox hbox=new HBox(20);               
        Circle img =new Circle(32,32,16);

        img.getStyleClass().add("imageView");
        if (origem.equals("0")) {
            tempFlow.getStyleClass().add("tempFlowFlipped");
            flow.getStyleClass().add("textFlowFlipped");
            chatBox.setAlignment(Pos.TOP_LEFT);
            hbox.setAlignment(Pos.CENTER_LEFT);
            hbox.getChildren().add(img);
            hbox.getChildren().add(flow);
        }else{
            text.setFill(Color.BLACK);
            tempFlow.getStyleClass().add("tempFlow");
            flow.getStyleClass().add("textFlow");
            hbox.setAlignment(Pos.BOTTOM_RIGHT);
            hbox.getChildren().add(flow);
            hbox.getChildren().add(img);
        //}       
        }  
        hbox.getStyleClass().add("hbox");
        Platform.setImplicitExit(false);
        Platform.runLater(() -> {
            chatBox.getChildren().addAll(hbox);                                    
        });      
    }

This bug happened because of the multiple internal nodes you have. Although I do not know what type of panel you are using for the chatBox I did some tests using it as HBox and I managed to reproduce the problem. It was not clear to me what type of screen you want to build, but resize will work if it is like this:

StringBuilder textoLongo = new StringBuilder();
textoLongo.append("Lorem ipsum dolor sit amet, consectetur adipiscing elit. Fusce et ligula et dui efficitur gravida.");
textoLongo.append("Etiam pretium condimentum quam sit amet faucibus. Suspendisse potenti. Donec nulla urna, pulvinar id ligula consectetur,");
textoLongo.append("pulvinar congue turpis. Donec convallis ultricies erat, ac bibendum augue tincidunt ut.");
textoLongo.append("Integer laoreet ipsum sed scelerisque aliquam. Nunc pulvinar urna nec tristique pulvinar.");
textoLongo.append("Praesent pretium tortor viverra tortor condimentum venenatis. Fusce a ipsum sem. Mauris malesuada venenatis ex,");
textoLongo.append("eu vestibulum est iaculis nec. Morbi finibus ligula vel commodo finibus. Ut gravida turpis id nisi sodales viverra.");
textoLongo.append("Donec lobortis ligula eu metus finibus congue. Morbi hendrerit, tellus non vestibulum ullamcorper,");
textoLongo.append("felis tortor facilisis orci, quis tempor justo nisl vitae magna");

Text text = new Text(textoLongo.toString());
TextFlow tf = new TextFlow(text);
tf.setPadding(new Insets(20.0,40.0,20.0,40.0));
chatBox = new HBox(tf);

Edit:

Below an implementation of a simple chat window:

// Chat
text = new Text("Bem vindo ao chat");
TextFlow tf = new TextFlow(text);
tf.setPadding(new Insets(20.0,40.0,20.0,40.0));

// Scroll pane apenas vertical
ScrollPane scroll = new ScrollPane(tf); 
scroll.setFitToWidth(true);

// Opções do chat e botão de envio
TextField chat = new TextField();
Button enviar = new Button("Enviar");
HBox opcoes = new HBox(5);
chat.setPrefWidth(250.0);
opcoes.getChildren().setAll(chat, enviar);
opcoes.setPadding(new Insets(20.0,40.0,20.0,40.0));

// Painel principal
BorderPane root = new BorderPane();
root.setCenter(scroll);
root.setBottom(opcoes);

enviar.setOnAction((ActionEvent) -> {
    String textoAtual = text.getText();
    String novoTexto = chat.getText();
    text.setText(textoAtual + "\n\n" + novoTexto);
});

Actually the problem was that there were two TextFlow inside the other, the first contained a maxWidth and the other did not. I removed the second TextFlow and it worked.
